Port 2 register
Note:
Port 2 Data Direction Register (P2DDR)
P2DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 2. P2DDR cannot be read; if it is, an undefined value will be read.
Setting a P2DDR bit to 1 makes the corresponding port 2 pin an output pin, while clearing the bit
to 0 makes the pin an input pin.
P2DDR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its
prior state after a manual reset, and in software standby mode. As the TPU and 8-bit timer are
initialized by a manual reset, the pin states are determined by the P2DDR and P2DR
specifications.
